'Ender's Game' Character Posters: Colonel Graff (and More) Revealed!

In Gavin Hood's ("X-Men Origins: Wolverine") "Ender's Game," an adaptation of Orson Scott Card's 1985 sci-fi novel of the same name, Earth, in the near future, is attacked by an alien race. The only hope to save humanity rests in children recruited by Harrison Ford's Colonel Graff for the International Military and trained by Ben Kingsley's Mazer Rackham.

In three exclusive new character posters, we get a look at some of the heroes who will fight against the Formics, an alien insectoid race bent on destroying humanity, including a stern-looking Colonel Graff, Hailee Steinfeld ("True Grit") as Petra Arkanian, and Nonso Anozie ("The Grey") as Sergeant Dap.

Check out the posters below and get ready for "Ender's Game," which hits theaters Nov. 1.
